Recent Hungarian water quality monitoring system uses 300 sampling points to classify surface waters into three quality categories that are mainly reflecting the viewpoints of different water uses. The suggested new system halved the number of the sampling points, while sampling frequency increased. The new system also includes metals, microbiological indices and organic micropollutants. The almost 70 constituents of the system are grouped into five water quality categories. The assessment is based on the value of 90 % relative frequency. The suggested new system is going to be introduced in practice from 1995 on.
